In St Denis, Bruno, chef de police, cant get a moments rest. Some rare bank notes have come to light that may have links to the legendary Neuvic train robbery in 1944. The investigation is fraught with issues. Bruno is also dealing with a wave of local burglaries, which have brought his old flame, Isabelle – and their complicated history – back to the town. Worse is to come. Tasked with piecing together these past crimes, Bruno now finds he has the more pressing matter of a body on his hands. He must now trace the links between past and present to restore peace in St Denis.
